My Favourite Triangle by David Fischer Copyright (C) 1999 David Fischer My Favourite Triangle has one corner at the North Pole. That vertex is a right angle. My Favourite Triangle has its remaining two corners on the equator. They're both right angles too. Cuz you see, My Favourite Triangle exists on the surface of a sphere, treated as two-dimensional positively curved non-Euclidean space. And it has three right angles. Cuz My Favourite Triangle is just too cool for Euclidean space. Yeah, My Favourite Triangle is just too fucking cool.
